It is possible to cycle home on an electric bike.
But don't do it again without someone on standby to collect you when the battery dies!
I set off at 11.15 with the bike on eco which means I do 75% of the work and it is not terribly fast but you don't notice any hills which is good as it is uphill pretty much all the way home. It died at 3pm about 7 miles from home and just before the one section of busy main road with no pavement. Typical.
At 4.45pm I reached The watersports centre about 3 miles from home absolutely shattered as cycling an electric bike after the battery has died is like cycling through thick treacle. And the hills oh god the hills!
I managed to collar a poor unsuspecting farmer with a landrover to carry me and bike the last 3 miles home. What a gent. So I was home by 5pm and straight into a hot bath.
